\item[/bin] general system executables
\pause
\item[/dev] device nodes
\pause
\item[/etc] configuration files
\pause
\item[/home] user directories

\subsubsection{Mounts}
\begin{frame}
\frametitle{The 'mount' Command}
\begin{itemize}
\item assign a filesystem to a directory
\pause
\item the kernel mounts the root filesystem on '/'

\item additional mounts performed by start scripts
\pause
\item mounts typically specified in '/etc/fstab'
\pause
\item 'mount'/'umount' can be performed at any time

\subsubsection{File Access Control}
\begin{frame}
\frametitle{Access Control}
\begin{itemize}
\item fundamental component (multi-user tradition)
\pause
\item permissions categorized as user/group/others
\pause
\item permissions are read/write/execute
